Definitions

  • the invention relates to a pipe clamp, in particular a pipe saddle clamp, for a main pipe, preferably of plastic, conveying a medium and comprising a saddle member, bearing elements, wherein the bearing elements are arranged on the saddle member, and preferably formed integrally with the saddle member, a tension unit wherein the tension unit comprises at least one band for encircling the main pipe, a band linkage and a clamping lever, wherein the band linkage and the clamping lever are each arranged at one end of the band or bands, and are opposite one another.
  • Pipe clamps of this kind mostly serve to connect outflowing pipes of main pipes and are as a rule fixedly clamped on the main pipe, whether as pipe clamps, which are subsequently welded, or as pipe clamps which are fixedly tensioned only on the main pipe.
  • WO 2016/023540 A1 discloses a saddle fitting which is fastened on the main pipe by means of a clamping band.
  • a sliding profile is located outside on the clamping lever or on the tension device of the clamping lever in which the clamping band is mounted, and the sliding profile makes it possible to tension the clamping band since, by turning the clamping lever or sliding profile, an area of the sliding profile spaced further away from the axis of rotation of the band end appears between the bearing shell and the clamping band and thus spaces out the bearing shell and the clamping band further away from one another.
  • the drawback here is that the tensioning distance becomes very short and the change in length from the loose clamping band or narrow area of the sliding profile to the tightened clamping band or the wide or further distant area of the sliding profile is small whereby fastening the saddle fitting on the main pipe is rather difficult since, as a result of the relatively precise band length which allows no large pipe tolerance, hanging the clamping lever in the bearing shell is difficult.
  • DE 44 37 410 A1 discloses a sealing device for sealing a pipe leak wherein a compress is fixed by means of a quick clamp device over a leak which is to be sealed.
  • the device comprises a long tensioning distance whereby this sealing device can be used on pipes of different diameters. So that a device of this kind can be fastened, however, high forces are required to turn round the clamping lever. This is counteracted by means of an additional tension spring wherein this has the drawback that as a result of the tension spring which is additionally required the device contains several parts and is then in turn more expensive to manufacture and assemble.
  • the present invention provides a pipe clamp for a main pipe conveying a medium.
  • the pipe clamp includes a saddle member and bearing elements, wherein the bearing elements are arranged on the saddle member.
  • the pipe clamp further includes a tension unit, wherein the tension unit comprises at least one band for encircling the main pipe, a band linkage, and a clamping lever.
  • the band linkage and the clamping lever are each arranged at one end of the at least one band and are opposite one another.
  • An extension is arranged on the clamping lever, and the extension is configured to be removed from the clamping lever after the tension unit is firmly clamped on the main pipe.
  • FIG. 1 shows a three-dimensional view of a pipe clamp according to an embodiment of the invention with the extension arranged thereon;
  • FIG. 2 shows a three-dimensional view of a pipe clamp according to an embodiment of the invention seen from the side of the band linkage;
  • FIG. 3 shows a three-dimensional view of a pipe clamp according to an embodiment of the invention in a tensioned state wherein the extension was already removed;
  • FIG. 4 shows a side view of a pipe clamp according to an embodiment of the invention in a tensioned state
  • FIG. 5 shows a side view of a pipe clamp according to an embodiment of the invention in a non-tensioned state.
  • Embodiments of the invention provide pipe clamps as well as their tension units, and a manufacturing process connected therewith, which enable an economic production, as well as a pipe clamp which has sufficient tensioning distance to allow for pipe diameter tolerances but which can nevertheless be easily clamped and easily fitted.
  • Embodiments of the invention provide for an extension to be arranged on the clamping lever on the pipe clamp wherein the extension is preferably designed as a separate part wherein the extension can be removed from the clamping lever after the tension unit is firmly clamped on the main pipe.
  • Pipe clamps according to embodiments of the invention are preferably made from plastic.
  • the pipe clamps include a saddle member with bearing elements arranged thereon.
  • the bearing elements serve to mount the tension unit wherein the bearing elements are arranged on the saddle member and the saddle member is formed as a part or in one piece.
  • the saddle member preferably has on the inner support side a heated wire winding in order to be welded firmly to the main pipe.
  • the pipe clamps moreover include a tension unit wherein the tension unit comprises at least one band for looping round the main pipe, a band linkage and a clamping lever.
  • the band linkage and the clamping lever are each arranged at the ends of the band and are opposite one another.
  • the band or bands are fastened on the clamping lever so that when the clamping lever is moved from the mounting position or non-tension position into the end position of the clamping lever, the distance between the band fastening on the clamping lever and the band linkage on the opposite side is clearly increased, whereby the pipe clamps can also be fastened on main pipes which are subject to a large tolerance range in relation to the outer diameter.
  • an extension is arranged on the clamping lever.
  • the extension is removed again from the clamping lever after the tension process and can be used for other pipe clamps.
  • the extension can thus be used multiple times.
  • the force is furthermore defined by the modulus of elasticity of the band or bands which are preferably made from plastic, as well as by their geometry which also has an effect on the force required.
  • a conventional hexagon key or socket wrench is used as the extension since this is generally always present with such assembly work.
  • the extension is preferably fastened on the clamping lever by screw or plug-in action which enables a simple quick fastening and the extension can be used on further pipe clamps and clamping levers.
  • the extension preferably has a thread or a multi-angled edge which is received by the mounting in the clamping lever.
  • the high torque which is required to firmly clamp the tension unit arises as a result of the long tensioning distance, that is, in the released state the band or bands is/are loose so that even main pipes which lie in the upper pipe tolerance range can be encircled without problem.
  • the clamping lever has brackets for engaging round the bearing bolts wherein other types of bearing are also conceivable.
  • the arrangement of the clamping lever can also be easily converted to the saddle member or to the bearing bolt.
  • the brackets preferably loop round the bearing bolt at a loop angle of more than 180°.
  • the tension unit preferably comprises one to four bands which loop round the main pipe; two bands are particularly preferred which are arranged on the tension unit.
  • the bands run parallel to one another and pass at the ends into the clamping lever and on the other side into the band linkage, wherein the band linkage is preferably formed as an axle wherein the axle preferably has a cylindrical shape.
  • a possible configuration of the invention is where the one end of the band or the one ends of the bands is/are arranged on the band fastening of the clamping lever, wherein the band fastening is spaced from the brackets which engage round the bearing elements or bearing bolts on the saddle member and serve as the axis of rotation.
  • the lever action is defined by the distance between the band fastening on the clamping lever and the axis of rotation which is formed by the brackets on the bearing bolt.
  • the band end or ends is/are connected to the clamping lever through injection moulding plastics which forms the clamping lever, or are formed integral therewith.
  • the bands can also be screwed, rivetted or clamped onto the clamping lever and the band linkage.
  • the band linkage is correspondingly arranged at the opposite band ends and is likewise formed by injection moulding plastics or by one of the aforementioned fastening alternatives.
  • the tension unit is designed in one piece when injection moulding the band ends with plastics to form a clamping lever and a band linkage which is preferably formed as an axle.
  • the complete tension unit can be formed as a one-piece injection moulded part by injection moulding the band and/or bands as well.
  • the fastening of the band or bands on the clamping lever has a distance of at least 15 mm from the brackets or axis of rotation.
  • a mounting is preferably arranged on the clamping lever wherein the mounting serves to receive the extension.
  • the mounting is preferably cylindrical.
  • the mounting likewise serves as a stop so that the clamping lever can only be moved up to a certain position which is defined as the end position. If the clamping lever were to be pivoted further beyond this position the band tension would in turn be reduced which would not be desired.
  • the extension can be simply fastened on the clamping lever and removed again after the tension process and used again for a further pipe clamp.
  • the indentation or opening in the mounting for receiving the extension is preferably designed for form-fitting engagement. It is more particularly designed as a multi-angle or thread so that a mounting is ensured which is secured against rotation, wherein a circular cross-sectional surface is also conceivable.
  • the band linkage is designed as an axle and is arranged in the bearing shells which are arranged on one side of the saddle member.
  • the bearing shells preferably comprise axial stops. This ensures optimum alignment of the bands on the external diameter of the main pipe when tensioning the tension unit.
  • Embodiments according to the invention further provide for the tension unit to be designed in one piece and the clamping lever and the band linkage are injection moulded on the band or bands or at the band ends by means of a plastic injection moulding process.
  • FIG. 1 shows a three-dimensional illustration of a pipe clamp 1 according to the invention with the extension 8 for firmly tensioning the tension unit 13 .
  • the pipe clamp 1 is fastened on a main pipe 12 and is fixed by means of the tension unit 13 .
  • the saddle member 2 is formed, preferably in one piece, with the bearing elements 3 , 4 arranged thereon.
  • the bearing elements 3 , 4 have on one side of the saddle member 2 the form of a bearing shell 4 , visible in FIG. 2 , and on the other side the form of a bearing bolt 3 .
  • Obviously other configurations would also be conceivable for a bearing element or bearing.
  • the tension unit 13 contains at least one band 9 wherein in the illustrated embodiment two bands 9 are provided running parallel to one another.
  • the clamping lever 5 and the band linkage 7 opposite this are arranged at the ends of the bands 9 .
  • the tension unit 13 is formed as one part since the band ends are injection moulded with the plastics of the clamping lever 5 and the band linkage 7 .
  • the band ends merge at the band fastening 11 into the clamping lever 5 and the opposing band ends merge into the band linkage 7 .
  • the brackets 6 of the clamping lever 5 serve to mount the clamping lever 5 on the bearing elements 3 and the bearing bolts 3 respectively.
  • the distance A between the bearing bolts 3 or the axis of rotation 3 and the band fastening 11 on the clamping lever 5 is made relatively large in order to have a large tensioning distance and also to enable looping round pipe diameters which are at the upper limit of the norm.
  • This enables simple mounting of the band linkage 7 which is preferably designed as an axle since the bands 9 are designed correspondingly long, which is easily visible in FIG. 5 in which the band 9 is shown loose.
  • the clamping lever 5 can be folded even further downwards in order to be able to loop the bands 9 round the main pipe 12 as easily as possible when fastening the pipe clamp 1 .
  • an extension 8 is arranged on the clamping lever 5 whereby the distance to the axis of rotation 3 is increased and a reduction in the force is allowed without affecting the torque.
  • the extension 8 is designed as a separate part and can be removed from the clamping lever 5 after the tension process and then used again when installing the next pipe clamp 1 .
  • the extension 8 is preferably arranged in the mounting 10 on the clamping lever 5 and interacts there with form-fitting engagement.
  • the mounting 10 is preferably designed as a hollow cylinder and the length is defined so that it serves as a restriction for the clamping lever 5 . This means that the clamping lever 5 can only be moved up to a certain position until the mounting 10 meets the pipe clamp 1 , as shown clearly in FIG. 4 . This prevents the clamping lever 5 from moving out beyond this setting of the end position so that the tension of the bands cannot be reduced again.
  • the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise.
  • the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
